We evaluated human leukocyte antigen (HLA)-DRB1 and -DQB1 alleles as genetic markers for Vogt-Koyanagi-Harada (VKH) disease in Mestizo patients in Southern California. Mestizo individuals with VKH disease (n = 29) at two institutions were evaluated. Typing of HLA-DRB1 and DQB1 genes was performed using DNA-based techniques. Gene frequencies were compared to Mestizo individuals living in Southern California. All patients had HLA-DRB1*01, DRB1*04, DQB1*03 or DQB1*05, or a combination of these genes. The gene frequency of combined HLA-DR4 alleles was increased when compared to controls. The frequencies of HLA-DRB1*0404 and DRB1*0407 were increased compared to controls, but were not significant after Bonferroni correction. Three patients had the HLA-DRB1*0410 allele; this allele was not found in controls. All HLA-DRB1*01 positive patients had the DRB1*0102 subtype. No HLA-DQB1 allele was significantly increased compared to controls. This study is the first to identify a possible association between HLA-DRB1*0404 and VKH disease, as well as to find DRB1*0102 and DRB1*0410 in Mestizo patients.
